de hereby declare the following to be av full clear, and exact descriptionof the invention, suc as will enable others skilledin the art" to which it appertairis to makeand use the same.

The present invention relates to a process and device, with the help of which vegetable and textile fiber, waste paper and woodfi verted-into. a bleachable papermafterial.

According to the present invent-ion thef :material to be treated is firstsoaked in. a re-} ceptacle filled with a solution oi caustic: soda. and water and then passedbet-weenj press rollers into'a churn or centrifugal-g machine. Any largergbodies or fibers re 'maining in the mass are crushed by the rollers before. entering the centrifugal machine; in the latter the mass is then churned'bysuitable heaters in order to loosen. it and gradually washed by the passage of water which removes the soda andgall substances notnecessa'ry for paper-making. The :resultingmass is now ready for further engine -or hand treatment and'vmay, if necessary, be

bleached in f known manner. During the treatment-- of the. mass in the churn or con-'- trifugal machine fresh material is introduced into the soaking receptacle, which will be sufficiently soaked by the time the first lot is churned and Washed, so that work can be continued without interruption, If the soaking requiresfa great-er leng'thof time than the churningandwashing, it,wil1.be

advisable; to provide two or .more soaking receptacles for each churn, sothatlthg Work: can be continued/withoutinterruption;1' necessary, the mass may be passed between} rollers a secondtime in: the centrifugal ma-[j chine.v law's: in? f Fbr. treatmentl byithe the follow ing 1 materials .-,are,':-;. dorm instanca-f. suitable :rv

Be it known that I, LU DWIGHHERLSUbjBCt 5' of Germany, residing at Nuremberg, -.Ba'-;. varia, Germany, have invented. certain new "and useful Improvements in Apparatus for: Treating VVa'ste. Vegetable "and Textile] Fiber for the Manufacture ofjPaper; and I and the paper may be colored, printed an, or written on. l As soaking solution the following been found suitable: 18 grams of caustie a to 1 liter voil water to-whiohmay be at? 0.01 liter of aqua ammonia to prevent a sible crystallization ofthe soda. Harda" tough materials may. be .soaked for sever hours-in thisysolu-tion; The churning however, beaccomplished in a much shame-r space oftime r 4 It; must be mentioned that .most of the above-mentioned 'materials, iean only he bleached after treatment accord ing to the present invention. 'x g gsrjav i \In thesoaking-receptacle rotating arms for stirringthemass may also be provided,

'in order to keep the mass in constant move ment. and

Reference being had to the acompanying drawings Figure 1 shows the apparatus for working the process according to the pres ent invention 1n. vertical, section; Fig. '2 is a plan View, 111- which, for. the sake of clear ness, thesoaking receptacle 1, rollers 2 and churn 9-, 11 are shown beside each other and a obviously be advisable to arrange these parts more or less in vertical alinement.

The soaking receptacle 1 is provided with radial fixed arms 3, between which the arms axis 5, driven by a'conical or other gear .16.

.From the soaking receptacle t e mass is -fed by a pipe 7'to the press rollers 2; said pipe may be arranged either attheside or below the receptacle and-is fitted with a suitable closure means, forinstance, a plug. 9 The rollers arearrangedeitlierabove a funnel leading tothe "ch urn 9,1 11, or in a box 8, lhayingjaepipe 35, communicating with the inner; tatingfcylinder 9 of the centrifugal 10$ advantage, with adjustable bearings and havea ribbedsurface. The pipe 7 is vpro- Ividedjwith a broad flat nozzle 10, so that the mass is'ffedpnt-othe rollers in the form of a e v The cy inder 9 of the churn iszrotatable which the liquids can pass into the outer cylinder 11; from the latter they pass off through a cock or valve 12. Cylinder 9 is fixed to an axis -13, rotated by asuitable conical .or other gear 14. In the center of the bottom of cylinder 9 is arranged an outlet 15: The hub 16 of the cylinder is. arranged to rotate aboutthe valve-box 17. E'aaid outlet 15 can be closed by the valve 19, arranged on the valve-rod l8, and actuated by a gearing 20 and hand-wheel 21.

In the cylinder 9'are arranged several rakes 22, having arms and radially adjustable in the slits 23 of the bearing-supports 24. In the drawing only one such rake is shown. The outer arms of the rake carry a brush 26, touching the sides of the cylinder 9, and arranged at anangle to said sides.

. The axis 13 is further provided with radial arms 27. If necessary, additional churn lshafts 29,- provided with arms 28, may be anranged in the cylinder ,9, and rotated,by a

pinion gear connecting with the axis 13. The outer cylinder 11 is provided with a water-gage glass 31 and an overflow 32, advisably having a tap or the like 33, so that said overflow can be closed when it is necessary to fill the cylinderto the brim for purposes'of cleaning.

The manner of working is as follows:

The rotationof the cylinder 9 throws the liquid mass against the sides, where the liquid separates from the mass and passes out through the holes into the outer cylinder 11..At' the same time the arms 25 of the rake 22 and if 'such areprovided, the arms '28 of the shafts 29,. churn the mass and 1 tear. it asunder. The brush 26 removes any substance sticking to the sides of the cylinder and forces it toward' the center.

A second-set of press-rollers 34 may be arranged vertically'inside the cylinder 9, as shown by the. dot-ted lines in'F-ig. 2.' Advisably these rollers will be placed in the way of the mass-scraped off the sides by the brush 26." These rollers will then be gonnec tedby gearing with the axis 13, simi-.

larly to the shafts 29.

It is obvious that the rake 22 ,may be given any other desired .form. Also, the sides of the cylinder 9 may be provided with large'holes or slit-sand a fine, sieve on the inside. Further, the pipe 7 may"be,provided with .a valve and operating gear similar to the cylinder outlet 15.

I If desired, thesoda contained in the liquid leaving. thev cylinder maybe by suitable treatment-again regained.

' .Theematerial resulting from the process here described is very suit-able as an in su'lating medium, for instance, instead of cork. For-this purpose, thelnass remaining inthe centrifugal machine is taken out, mixed'with'chromic acid and size and then pressed. A goodproportion is; 200 kilogramsfof the mass, 0.5 kilograms -of-chen1i.-'

cally pure chromic acid and 4 kilograms of size. It must further be mentioned that this process and apparatus may also be used for cleaning linen; or wool waste and the like. For this pui'pose, the materials to be cleaned are placed in the above-mentioned soaking solution for a suitable period and then washed until all traces of soda are removed. Also here it will be found advisable to soak the material under treatment in one receptacleand-then to remove the soda in a second receptacle and to keep the material in constant movement by means of rotating arms in both receptacles.
